Study aims to evaluate the improvement of heavy metal polluted soil in different soil environments with different concentrations of heavy metal. Phragmites autralis is a kind of tree which has an ability to accumulate high level of heavy metal, about 80 – 90% of the total content of heavy metal accumulated in the root. The total concentration of heavy metal reduces significantly: As decreases 0,92 times, Pb reduces 0,83 times, Cd declines 0,67 times, Zn lessens 0,86 times. Mobile processor efficiency of As reachs 99%, Pb is 96%, Cd is 95.4% and Zn reachs 96.6%.
